Command Reference

show port

Use the show port command to display port status and counters.
show port [mod_num [/port_num]]

Syntax Description

mod_num (Optional) Number of the module. If you do not specify a number, the ports on all modules are shown.

port_num (Optional) Number of the port on the module. If you do not specify a number, all the ports on the module are shown.

Default
This command has no default setting.

Command Type
Switch command.

Command Mode
Normal.

Example
This example shows how to display the status and counters for port 4 on module 3:
Console> show port 3/4
Port  Name               Status     Vlan       Level  Duplex Speed Type
----- ------------------ ---------- ---------- ------ ------ ----- ------------
 3/4                     inactive   1003       normal   auto  auto TokenRing
 
Last-Time-Cleared

Table 6-27: show port Command Output Fields
Field Description

Port Module and port number.

Name Name (if configured) of the port.

Status Status of the port (connected, notconnect, connecting, standby, faulty, inactive, shutdown, disabled, or monitor).

Vlan VLANs to which the port belongs.

Level Level setting for the port (normal or high).

Duplex Duplex setting for the port (auto, full, fdx, half, hdx, a-half, a-hdx, a-full, a-fdx).

Speed Speed setting for the port (auto, 10, 100,155, a-10, a-100, 4, 16, a-14, a-16).

Type¹ Port type, for example, 10BaseT, 10BaseFL MM, 100BaseTX, 100BaseT4, 100BaseFX MM, 100BaseFX SM, 10/100BaseTX, TokenRing, FDDI, CDDI, and RSM.

Security Status of whether port security is enabled or disabled.

Secure-Src-Addr Secure MAC address for the security enabled port.

Last-Src-Addr Source MAC address of the last packet received by the port.

Shutdown Status of whether the port was shut down because of security.

Trap Status of whether port trap is enabled or disabled.

Broadcast-Limit Broadcast threshold configured for the port.

Broadcast-Drop Number of broadcast/multicast packets dropped because the broadcast limit for the port was exceeded.

Align-Err Number of frames with alignment errors (frames that do not end with an even number of octets and have a bad CRC) received on the port.

FCS-Err Number of frame check sequence errors that occurred on the port.

Xmit-Err Number of transmit errors that occurred on the port (indicating that the internal transmit buffer is full).

Rcv-Err Number of receive errors that occurred on the port (indicating that the internal receive buffer is full).

UnderSize Number of received frames less than 64 octets long (but are otherwise well-formed).

Single-Coll Number of times one collision occurred before the port successfully transmitted a frame to the media.

Multi-Coll Number of times multiple collisions occurred before the port successfully transmitted a frame to the media.

Late-Coll Number of late collisions (collisions outside the collision domain).

Excess-Col Number of excessive collisions that occurred on the port (indicating that a frame encountered 16 collisions and was discarded).

Carri-Sen Number of times the port sensed a carrier (to determine whether the cable is currently being used).

Runts Number of received runt frames (frames that are smaller than the minimum IEEE 802.3 frame size) on the port.

Giants Number of received giant frames (frames that exceed the maximum IEEE 802.3 frame size) on the port.

CE-State Connection entity status.

Conn-State Connection state of the port, as follows:

Disabled--The port has no line module, or was disabled by the user.

Connecting--The port attempted to connect, or was disabled.

Standby--The connection was withheld or was the inactive port of a dual-homing concentrator.

Active--The port made a connection.

Other--The concentrator was unable to determine the Conn-State.

Type Type of port, such as A--A port and B--B port.

Neig Type of port attached to this port. The neighbor can be one of these types:

A--A port

B--B port

M--M port

S--Slave port

U--The concentrator cannot determine the type of the neighbor port.

Ler Con Status of whether the port is currently in a LER condition.

Est Estimated LER.

Alm LER at which a link connection exceeds the LER alarm threshold.

Cut LER cutoff value (the LER at which a link connection is flagged as faulty).

Lem-Ct Number of LEM errors received on the port.

Lem-Rej-Ct Number of times a connection was rejected because of excessive LEM errors.

Tl-Min TL-min value (the minimum time to transmit a FDDI PHY line state) before advancing to the next PCM state.

Last-Time-Cleared Last time the port counters were cleared.

¹ These fields will change according to the system configuration.
